' Specification of Letters Patent,

Patented May 14, 1907.

Application filed August i906. Serial No. 382,297.

To all whom it may concern.-

Angeles, in .the county of Los Angeles and State of California, have invented new anduseful Improvements in' Car Tr-ucks, of which hold the-parts together, th'ereb. allowing the the following is a specification.-

This invention relates to improvements on lthe inventions heretofore made by me and shown anddescribedj-in two certain appli' cations for atents filed in the United States- Patent 0 ce as follows:(1)Scctional" kin bolt for railway cars, Serial Nol 303,778,

ofithe ordinary'const'ruction; to make the file ,M arch 2, 1906.; and? (2) se ctional king bolt ferirailway cars, Serial Number 322,771,

filed June 21, 1906,- and in which-a plications I have s'hown'a sectional king-b0 t connect ing the .carbe'am and truck beam of; a railway.

car.

Objects of this invention are r to simplify and reduce the numberof parts and to d s-- .pense with parts which might interfere with the applicatlon of the invention to car trucks device more readil v g the trucks f'rom the car body; to provide a simpleand efiective'pivotal connection between the car-body "and car truck, which will allow the necessary movements ofthe car truck caused by the angularities or curves of thetrack, Without transmitting to the car body-suchmovements of the truck; at the same time making provision for the ready and direct transmission-- of the tractive force either'from the carbody to the car truck or from the car truck to the car body, as the case may be for self-propelled ordrawn cars; to providefo'r' readily oiling the pivotal connection between the car body and the car truck. j

By-means of this invention the car truck is i always freely pivoted to the car body, and

alldanger of jamming the pivotalconnection, so that the trucks will not move freely around 1 safe strong couplingbetween the car body and'truck'that'will'do away with all liabilit f of lifting any ofthe-wheels of'tlie truck 0 a'curve', is entirely done away with.

An object of this invention is to provide a thergroundgln case the car'jbody' is-brou an angle with the track as occurs w en a tram car startstoclimbasteepjhill, v 4 principle of intention regard to ap 'licable to cars to' provide for readily. et'aciiin 7 connecting said members, together. meansshown nthe drawmgs :compmse I: one of-its-features of novelty is that a solid v Be it known that 1, ROBERT H. BROWN, a. citizen of the United States,-residing at Los .stud and the collar to form so id continuous beari'ng' facesfrom side to side and allowing such bearing'faces to be curved to allow the requisite rocking movement between the parts to give the required flexible joint.

By removing the detachable bars 6 and so porting the car body, the car truck can ie 25 readily removed.

, The beams 9 and 13 and other parts m' y bemade of any suitable material, preferably wrought, rolled, or cast'steel'or iron. The beam and collar fastened, thereto form aseat for the rounded end of'the in to allow the pm to sway relative'to the earn and collar. The seat for the 'in engages orrests on the lower member at ack and front of the pin 3,- as seen at'5 in'Figs. 1 and 2where the bottom 3 5 of the flange orlug 5 is rounded in cross section to rock on the lower member 20. The

shim extension 17 of the 'pin enables the attend antto make good' any wear by substituting thicker shims as the wear occurs,,thusto 40 cause the u 'per pivotal member to be mainlysu orted ythepin. I

e two bars 6 shown in Figs. 4, 5, and 6 are employed for maximum security and strength, but one of them alone will serve-to prevent separation of the sections 3 -and 4 and in some cases one of such bars may be dis ens'ed'with.
